  A number of new bicyclic organotin compounds have been synthesised by treating the corresponding organic halide with (trialkyl- or triarylstannyl)sodium in liquid ammonia. syn-7-Bromo-2-norbornene yielded mainly the anti-7-trimethyltin derivative when treated with (trimethylstannyl)sodium, but gave a tricyclic compound on reaction with (triphenylstannyl)sodium. anti-7-Bromobenzonorbornadiene gave a

  The present invention relates to a method for preparing an ethylene-based elastic copolymer, and more particularly, to a method for preparing an ethylene-based elastic copolymer by using a catalyst composition for preparing an ethylene-based elastic copolymer, the catalyst composition comprising a binuclear constrained geometry transition metal compound, as a main catalyst, having a structural advantage to obtain a high-molecular-weight ethylene-based elastic copolymer due to a high polymerization activity and comonomer reactivity because the binuclear constrained geometry transition metal compound has a structure in which cyclopentadiene ligands of two constrained geometry catalysts are linked by 1,4-phenylene, and one or more cocatalyst compounds selected from the group consisting of an organoaluminum compound, an organoaluminoxane compound, and a boron compound.

  本发明涉及一种制备乙烯基弹性共聚物的方法，更具体地，涉及一种使用催化剂组合物制备乙烯基弹性共聚物的方法，该催化剂组合物包括双核约束几何过渡金属化合物作为主催化剂，由于双核约束几何过渡金属化合物具有环戊二烯配体的结构，两个约束几何催化剂的环戊二烯配体通过1,4-苯基相连，因此具有高聚合活性和共聚单体反应性的结构优势，能够获得高分子量的乙烯基弹性共聚物。催化剂组合物还包括从有机铝化合物、有机铝氧烷化合物和硼化合物组成的群体中选择的一个或多个协同催化剂化合物。

  Provided are a metal-ligand complex, a catalyst composition for ethylene-based polymerization including the same, and a method for preparing an ethylene-based polymer using the same. Since the metal-ligand complex of the present invention in which a certain functional group is introduced to a certain position has high solubility and catalytic activity, the catalyst composition comprising the same for ethylene-based polymerization including the same may produce an ethylene-based polymer having excellent physical properties.
